NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
820 PM CDT Friday Aug 1 2014 


Sounding discussion... 


Routine flight terminated over Lake Pontchartrain about 4 miles 
east of The Causeway about 21.4 miles in altitude. Airmass 
continues to moisten this evening with a precipitable water value 
of 2.08 inches. Cape of 959 and lifted of -3 on this flight. Cell 
movement will still be slow with storm motion of 6 knots. 
Convective temperature of 84 degrees...which would likely be 
reached by middle to late morning tomorrow. Winds were light easterly 
for about the first 5000 feet...then west to northwest above that 
through about 100 mb before becoming easterly. A 46 knot maximum wind 
at about 42k feet. 35

Previous discussion... /issued 357 PM CDT Friday Aug 1 2014/ 


Discussion... 
frontal boundary has stalled across the forecast area today. 
At this time...the front is draped along a line from near Baton Rouge 
southward to the coast. Dewpoints east of the boundary are quite dry 
in the middle to upper 60s. West of the front they are in the middle 70s. 
The rain shield however seems to be more oriented based on the 
Omega maximum and surface low position. Medium range and mesoscale models 
agree that a general down trend of convection can be expected this 
evening although some lingering showers are possible throughout the 
night...moreso northwest of a hum to asd line. Tomorrow will be similar to 
today but with more showers spreading further east to include the 
southshore of Lake Pontchartrain and Mississippi coast. The 
combination of lowered heights...continued column saturation and 
convergence zone along old frontal boundary should allow for more 
shower and thunderstorm enhancement on Sunday so have kept previous 
likely category of probability of precipitation. 


The Bermuda ridge will build westward across the Gulf of Mexico 
middle of the week and Onward. This may be enough to cutoff moisture 
flow from the southwest which would lower rain chances to 20 percent 
or less. Until then...expect daily coverage of 40 to 50 percent with 
temperatures still a few degrees below normal. Overall rainfall 
totals of around 2 inches through the forecast period are possible 
with model soundings showing precipitation water around 2 inches as well. 


Meffer 


Aviation... 
first 6 hours of forecast was based mainly on radar trends and 
mesoscale models which indicated the greatest chance and highest 
coverage of rain showers would continue from kbtr to kmcb and possibly east 
to near khdc where mention of some limited visibilities and rain showers/thunderstorms and rain are 
in the tafs. The remaining airports to the east and south are less 
likely to see prevailing...lower than VFR conditions from rain showers...and 
less likely to see thunderstorms and rain...so have mainly only added vcsh. Confidence 
of location of rain showers and lower conditions later this evening through 
Saturday morning was insufficient to go below VFR in the tafs at 
this time. 22/dew point 
&& 


Marine... 
weak surface ridge will meander around the Gulf of Mexico from today 
through the middle of next week. This will keep winds light and 
variable at less than 10 knots with seas mostly 1 foot or less.
